Abstract

The current research aims to determine the role of the fuzzy failure mode and its effects analysis technique in improving the effectiveness of the overall equipment in the Al-Ittihad Sugar Factory in Iraq. The independent variable is represented by the failure mode and its effects analysis technique consisting of the risk priority number that we obtain from multiplying the factors (severity, occurrence, and detection). Which is the main input to the fuzzy logic that evaluates and prioritizes risks, based on the fuzzy inference system consisting of three steps (fuzzification, fuzzy rules, and defuzzification), which was implemented by the (MATLAB) program according to the (Mamdani) method. The research population represented the centrifugation station, while the research sample numbered (16) batch centrifugal. The research used the applied approach to determine the reasons for the low rates of equipment effectiveness with its three indicators (availability, performance, and quality) as the dependent variable. The research adopted some statistical methods (correlation coefficient and simple and multiple linear regression equations). The results of the research showed that there is a correlation and a statistically significant effect between fuzzy failure mode and its effects analysis technique and overall effectiveness of the equipment.
